[llvm-commits] CVS: llvm/include/llvm/Target/TargetOptions.h

[Evan Cheng]

Changes in directory llvm/include/llvm/Target:

TargetOptions.h updated: 1.8 -> 1.9
---
Log message:

Added option -enable-finite-only-fp-math. When on, the codegen can assume that
FP arithmetic arguments and results are never NaNs or +=Infs. This includes
ignoring parity flag (PF) when checking for FP equality.
